PushtiMarg

Pushtimarg is one of the sects of Vaishnavism. Pushtimarg was founded by Vallbhacharya Mahaprabhuji in early 16th century.
Pushtimarg mainly focuses on Krishna bhakti and it was followed and spread widely by descendants of Mahaprabhuji and Gusainji.

Path to receive grace via performing Seva of Thakorji is pushtimarg.
The first principle of pushtimarg is the devotion to Thakorji. Ritually all Vaishnav should pusht Thakorji with the permission of respective Guru and can start devoting to Thakorji.

In pushtimarg people believe in Lord Krishna and they perform Seva of Thakorjin as Shree Krishna. Vaishnav's start performing Seva from the morning when Thakorji wakes up too late evening when Thakorji goes to sleep.

It's a belief that if Seva is performed by love and affection then and only then Thakorji gives Darshan or play with us.
